ACH-30200 Silver-Filled Epoxy Resin

DEFINITION

High silver-filled content mono-component hybrid resin for die attach. PROTAVIC® ACH 30200 is useful when a high level of thermal and electrical conductivity combined with a good properties of moisture resistance is required.

APPLICATION PROPERTIES

The PROTAVIC® ACH 30200 epoxy adhesive combines an excellent adhesive properties.
Its good latency enables it to be kept at 20 ± 2°C for 1 week with a little increase of viscosity, so the viscosity remains virtually unchanged throughout the working day. The long pot life ensures that the product remains at a reasonably constant viscosity and facilitate application.  Its rheology makes the product useful for an application by dispensing.

METHOD OF USE

  1. Take the package out of the freezer at not more than 1 hour before use in order to prevent any re-absorption of moisture.
  2. Work on clean surfaces or clean all surfaces in order to remove any dirt or grease. Do not deposit the adhesive on a substrate which has just been cleaned with chlorinated solvents.
  3. Apply the adhesive (by dispensing)
  4. Cure using one of the curing cycles compatible with the components, the substrate and the manufacturing conditions.
